MECHANICAL MOVEMENT FOR WASHING-MACHINES.

Specification of Letters Iatent.

Application filed October 17, 1906. Serial No. 339,388.

To all whom it may concern:

Be It known that I, WILLIAM H. Voss, a citizen of the United States, anda resident of.

. Davenport, in the county of Scott and State able elevation by legs a,and

of Iowa, have invented certain new and useful Improvements in MechanicalMovements for Washing-Machines," of which the following is a clear,full, and exact description.

My invention relates to the actuating mechanism of washing machines, andits obj ect is to provide means for utilizing the momentum of afly-wheel to assist in actuating a stirrer-shaft driven by areciprocating lever and particularly the reversing movement of saidshaft and thus greatly assist in rendering the manual working of themachine less arduous. This I accomplish by the mechanism hereinafterfully described and as particularly pointed out in the claims.

In the drawings :Figure'.l is a side elevation of a washing machinehaving my improvements applied thereto. Fig. 2 is a vertical centralsection thereof taken on dotted line 22, Fig. 3. Fig. 3 is a plan view.Fig. 4 is a detail view showing the gear connecting the reciprocatinglever and stirrer-shaft] on a slightly larger scale.

. Referring to the drawings A represents the tub of a washing machinesupported at a suitrepresents the cover of the tub hinged, as shown inFig. .3, to

the segmental top piece I) that is securely fastened to the upper edgeof the tub.

C represents a rotar reciprocal stirrershaft, which is journale insuitable bearings c in the center of the cover B, and has a suitablestirrer-head C secured on its lower end within the tub. Above itsbearings the stirrer-shaft is made square in cross-section and extendsup through a pinion D, with which it rotates but can move independentlyin a longitudinal direction. This stirrer-shaft, after passing throughthe boss of pinion D, extends up into a suitable sleeve journaled in thevertical bearing 6, supported in the u per end of the frame E. Bearing eis'of such ength that its-lower end engages the upper end of the boss ofthe gear and prevents its displace.- ment from the position shown in thedrawlugs.-

which is fulcrumed a lever F. whose upper ortion is provided with ahandle of sufficient ength, and Whoselowerportion is formed into asegmental gear 9 that engages the upwardly Projecting laterally from theupper end of the bearing 6, is a suitable stud f upon projecting teeth hof a straight horizontally disposed double rack G.

ltack G is provided with a series of laterally projecting teeth j thatmesh with gearD, with which it is he t in engagement by means of asquared horizontal guide-bar I-I, upon which guide-lugs I, I, projectingfrom the ends of said rack, are slidingly mounted. This guide-bar ismaintained in about the same horizontal plane as the gear D and rack G,by havingits ends secured in short standards 7c, is, removably securedto the cover, substantially as shown.

At one end the rackG is-provided with upwardly projecting pivotal lugsm, between which the adjacent end of a horizontally disosed link J is,preferably, removably secured.

his link extends in the same direction as rack G, and has its endfarthest from the rack pivotally and adjustably connected to the upperend of a rocking-beam K, which latter is fulcrumed between the lugs of abracket M, suitably secured to the side of the tub near its bottom. Thelower end of beam K extends to a suitablepoint below the plane of thebottom of the tub, and is connected by a pitman N to the crank-pin ofgear 0, journaled on a stud projecting laterally from the lowerextremity of an L-shaped hanger I, which latter is secured to anddepends down from the bottom of the tub. T his gear 0 engages a pinion1' on the adjacent end of a horizontal shaft Q, journaled in bearings inthe angle or bend of the hanger P, and in bearings R depending from thebottom of the tub near its circumference, and has a suitable flywheel Tsecured to its outer end.

In 0 eration, when the lever F is reciprocated ack and forth, thesegmental gear 9 engages and reciprocates rack G, which, through themedium of the pinion I) imparts a rotary reci n'ocal movement to thestirrershaft and stirrer-head. cates it rocks the beam K, through themediumof the link J, and said beam by means of the pitman N revolvesgear 0, and the latter drives shaft Q through pinion 1', with which itintermeshes. When the shaft Q is revolved the fly-wheel im )arts amomentum thereto, which, through the train of the mechanical devicesillustrated and described, materially assists in actuating the rack G,and in reversing the same at the ends of the reciprocal throw thereof,and thus lessens the expenditure of physical force, which heretoforewasdemanded of the operator, particularly when reversing the movement ofthe stirrer-shaft-at each end,

of the reciprocal throw of lever F. Y
